Abstract (en)
[origin: WO2021188758A1] An electric machine, which may operate as an electric motor or generator, that address performance and manufacturing shortcomings in various motor design approaches particularly transverse flux, axial and radial flux motors with higher torque, higher RPM, and lower core losses and lower cogging. An exemplary electric machine incorporates shape monolithic components such as the armature teeth or connector ring, armature ring, concentrator teeth or concentrator ring formed by Soft metal Composite (SMC). Magnets may be configured between the concentrator teeth to form a magnet ring having a plurality of magnetic poles. The armature flux paths may be shared between phases. The air gaps may be axial and extend between armature teeth and concentrator teeth and the magnetic poles configured between the concentrator teeth. The armature, concentrator teeth and magnetic poles may extend radially and alternate along the axial axis of the electric machine, producing axial and/or radial airgaps.
